Inequalities Set 21

Directions (1-5): In each of these questions the symbols @, #, $, % and * are used with different meanings as follows.
I. ‘P @ Q’ means ‘P is not smaller than Q’.
II. ‘P # Q’ means ‘P is not greater than Q’.
III. ‘P $ Q’ means ‘P is neither smaller than nor greater than Q’.
IV. ‘P % Q’ means ‘P is neither smaller than nor equal to Q’.
V. ‘P * Q’ means ‘P is neither greater than nor equal to Q’.
In each question, four statements showing relationships have been given, which are followed by four conclusions I, II, III and IV. Assuming that the given statements are true, find out which conclusion(s) is/are definitely true.
